Why do AC Vents stayed closed on 1998 Buick LeSabre?

Under the hood in front of the transmission dip stick is a vacuum line. If it is disconnected or split it will make the air vents not work. If that's not it check your fuses.

I just fixed a similar problem on my 95 LeSabre, got info from this website. http://www.imcool.com/articles/aircondition/fix_vacuum_line.htm

Make sure refrigerant is fully charged. Does it have dual climate control? Perhaps passenger side sensor is not working properly

The vacuum supply line from the engine is disconnected or broken. When the vacuum supply is cut off the system defaults to the defrost mode.

There is a conduit with a fastener at the end. When I obtained my 2005 Buick LeSabre my rear air vents seemed to blow less than I had expected. After further inspection, I discovered that the conduit was not attached to the vent stack. So I played with it until I got it to slide into the vent stack and it seems to work as I would have expected at present.

To change the CD player you need to disassemble the dash. First remove the 4 vents. There will be screws there. Also remove the woodgrain trim, there's screws there too. remove them and then pull the black dash piece out.

The 1984 Buick uses vacuum lines to change air flow from defroster to ac vents. Check the entire vacuum system for leaks.

There may be something blocking the deflectors from sending air up there.

If the heat selector will not switch from defrost to the dash or foot vents on a 1992 Buick, it is possible that the cable connected to the vent is broken. When the selector is moved from defrost, a cable opens the other selected vents on the heater.

There are heater doors on the heat blower box that direct the path of the heat. Apparently the heater door to the floor vents is stuck closed.

side floor vents are manually closed, been along time but i think that's right.

I don't know about a 94 roadmaster, but on my 95 lesabre, i had to take the HVAC vents out first. Pry up on the bottom of them (very gently!) and they should pop out. There were screws holding the dashboard in behind where the vents used to be. Assuming you are removing the dash to install a new stereo or climate control unit, they all "pop" out. No screws. Best to throw the car…

there is a blend door not operating properly the dash will have to be removed to repair most likely Read this article: http://www.imcool.com/articles/aircondition/fix_vacuum_line.htm I'm having the same problem. Jim

Take off the top dash cover.. There are some screws by the defrost vents, take off the tri piece to find those. And then underneath there will have about five more. Look up where the gear shift is to find these ones. Once you remove the dash cover, you will see a red box on the passenger side.

Have the cabin air filter changed.

I don't directly know about a '92 Estate Wagon, but I have a '95 LeSabre, and you have to start by carefully prying up on the vents with a small screw driver to pop them out. Then take out the screws that you just uncovered. This should allow you to remove the black plastic trim piece that spans the whole dashboard. After that, you can get to the screws holding the radio in and just…

Open, so the moisture can escape.

you have to remove the wood grain trim peice by just pulling then remove the air vents there are about 7 screws under the wood trim and then another 1 under each vent then open the glove box to get to 2 more screws then remove it once you remove all the screws the dash should lift right out

Might have a bad vacuum motor for one of the doors for the ducts. Most likely U have a Vacume leak @ the Vacume Canister or a bad Vac hose.The hoses are very small(about 1/8 or 3/16 inch)Some- times its a Actuator 4 the mixer doors but mstly its just a small Vacume leak.Check the hoses from the intake manifold to the fire-- wall,Thet T off & becme very small.

WHICH VENT If you're talking plumbing roof vents or soffit or ridge attic air vents; absolutely not!! I can't thing of a single vent that would be opened and closed at will.

probally closed or clogged

I have a 99 Ford F250 super duty. When I turn on the fan to the heater and AC I can hear air moving in to the vents. No air moves out of the vent on any setting. It is like all vents are closed. what could be the problem. I have replaced the switch. I check the blower motor.

on your car it is a defalt mode for air to blow out defrost when there is no vacumn from the engine so you should look for a broken vacum line or see if it has come unplugged on the engine.

Not really, there's not much airflow when the furnace is not running.

Your air conditioning cool air is routed to the various vents by routing doors. A malfunctioning routing door can be stuck and remain closed.

Yes, especially if you live in an area where the humidity is higher. The vents allow moisture in the air to escape from under your house. Moisture trapped under your house can cause mold and floor rot. The vents should always be open a little. This is to ensure you don't get a sick home and so the air circulates through the house. That's if these are hvac vents. If the vents go to the…

first you snap off the wood trim from the dash then you take 3 screws out, one at the bottom left of the trunk release the other at bottom of passenger airbag and the other one is located to the bottom right of the passenger airbag. After that pop out the 4 air vents, inside there is one skrew in each of the vents slot tak those out too. Put the Buick in the lowest…

The vents in the CLK can be closed completely by moving the wheel in the center to the closed or open position or adjusted by using the tab to focus the vent blades right/left or up/down.

could be that your vent on your dash is open.it will pull outside air in and if you are using the ac the air coming in the vent is from the hot weather outside.........there is a little spinning knob between the vents , make sure it is closed

change the cabin air filter located behind a panel in the glove box

there is a vacuum canister in the engine compartment. It probably has a tiny leak. seal with silicone

keep your ps3 vents always clean and well maintained. Keep ps3 out of closed spaces so it wouldnt overheat.

the battery in under the rear seat all you do is left on the front of the bottom part of the seat and BING BOUTA BOOM theres the battery, just undo the mount, and untightin the battery terminals and get ER DONE Not so FAST! This car requires a VENTED BATTERY. This vents the battery gases out the bottom of the vehicle. A conventional battery's out-gassing to the interior of the car would be extremely…

Smokers are designed with vents on both the top and bottom of the smoker unit. Typically, the bottom vents are used to fan or fuel the flame inside. Adjusting the bottom vent either flames your fire or smolders it. The top vents are the ones that are typically used to control the heat inside the smoker. The more you open the vents, the more heat will escape out. The tighter you keep them closed, the…

== == There are three electronic actuators under the dash: one is for the defroser, one is for the bank of four passenger vents and one ( this is you) sends air to the two driver side vents, the two mid-dash vents and the two rear vents. Either this actuator is faulty, or there's a problem with the electrical delivery system; mainly, the whole climate control panel in your dash (dealer cost: about $700.00).

To remove the stereo first you have to disassemble the dash obviously. So to start that,you have to remove the wood trim under the black piece of dash, after that you have to pop out the four vents in the black piece. This is simple to do, all you do is turn them to the right or left and push it on that side and it should pop out. Then remove all the screws of…

There are two. Most oil changing places will offer to replace them for you. It can make quite a difference by eliminating the stink out of your A/C vents...squeezing

Yes! Close off the vents and close the door, then you will not waste the energy of heating and cooling the closed off area.

they are photocells....they adjust the headlights from daytime lights to headlights when it gets dark out and vise-versa

Attic ventilation can be as important in the winter as in the summer. The vents allows the air space in the attic from having a build up of moisture. With the vents closed, there could be times the humidity in the attic would be high enough to cause mold and mildew on the lumber, especially the roof sheeting. In the summer the vents allow heat to be vented out and in the winter they allow…

first thing to check is the fuse

While running your air conditioner, the vents should be closed so that warm air from out side do not enter into the room,which may cause damage to the machine in the long run and it will fetch more time to cool the room.

No heat, Heater Hose Replacement I had/have the same problem on my 92 Lesabre, I replaced the top heater hose which I believe controls the two most right vents and I have "heat" from those two vents. I don't have heat all the time from the left vents because I couldn't change the bottom heater hose, it's very diffcult to reach and get out and replace, I will try again this coming spring, pray for…

Even when your vents are closed, air still is being pulled into the car. The musty smell means you inside cabin air filter needs to be changed. You can gain access to the filter through your glove box.

Your positive crankcase ventilation valve, or PCV, is probably stuck closed. The PCV vents crankcase pressure from the engine into the intake. When this valve sticks closed the pressure has to escape somewhere and it normally will escape through the dipstick tube.

Magma or lava vents and gas vents. Also fumarole.

Return air vents.........

The area of Sept-Vents is 12.52 square kilometers.

The area of Treize-Vents is 19.12 square kilometers.

With either gable vents, soffit vents or ridge vents. The more the better
